The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.6.3, 9.5.7, 9.4.12, 9.3.17, and 9.2.21. This release fixes three security issues. It also patches a number of other bugs reported over the last three months. Users who use the PGREQUIRESSL environment variable to control connections, and users who rely on security isolation between database users when using foreign servers, should update as soon as possible. Other users should plan to update at the next convenient downtime.
